t Claims. (olf iz--iil This invention relates to tools and moreparticularly to tools designed for trimming and Waiting the edges ofshoe soles and heel lifts. `Af pai- V ticular object of the invention isto provide coinbination tool comprising a rotary trimmer and a rotaryWaiier or nisher, one of the features of the invention being the`provision of a'. pair of gages mounted upon the tool head andcooperating with the trimmer and with the Waxer which gages aresimultaneously adjustablelby a single operating mechanism for varyingtheir setting.y

Another object 'of the invention is the provision of a novel formofcutting blade for the trimmer,

d and the provision. `of a simpleand ooivenient means fordetachablymounting the cutting blades in the trimmer. Afstill further object ofthe invention is to provide a Waiter of improved con-A struction.

The present application is a substitute for" abandoned applicationSerial Not 677,130', filed June 22,`` in s'of'ar as the subject matteris disclosed therein. t d u The inventionfvvill be better understood`from t the following detailed desciiption of a preferred and Waxing theedges of the embodiment, thereof, reference being had to the annexeddrawing in which:

Figure 1 is a View of the tool in side elevation;

Figure 2 is a sectional View of the tool shown in Fig. l;

Figure 3 is an end elevation of the tool; and

Figure a is a detail View taken on the line 4;-4 of Fig. 3 showing themanner in which the blades are secured in the trimmer.

The tool illustrated in the drawing is particu- "larly useful in shoemanufacture for trimming shoe soles and heel lifts. i

Referring to the figures, reference numerall 1 indicates the end of arotatable shaft upon which the tool head 2 is mounted. The headcomprises a trimmer T and a Waxer W and is provided with a socket 4 forreceiving the end of the shaft l as shown in Fig. 2. A cylindrical plug5, threadv edly mounted within the end of the tool head 2,

supports a series of cutting knives 7 at spaced i or disposed at anangle to the axis of the head as shown in Figures 1 and 4 and areretained in their grooves by means of a flange 8 on the end of the plug5. A guard cap 9 held by a screw 10 threadn ed into the end of plug 5covers the outer edge of the blades. Each of these blades upon its atv"Working edge is provided with a straight section 11 and a terminalbeveled `section 11d which latter imparts a chamfer to the vvoirk' beingoperated upon.-` `The blades may be rnove'dby taking von the guardcap Qand backing-tle plug 5 fai" enough to permit the Withdrawal 'oftlieblades from the overhangiiig grooves 6.l

The outer or operating end of the tool head is enlarged as showninFigikZ and provided with a circular recess 12 within lia/nien issndabiy nasa a oylindiial ring 13 constituting ag'ge for th trimmer Theend of the head upon its exile` rior serves as the vvaXer W and isconstituted of a smtn menen eylizldA-lsprovided at cirn cumferentiallyspao'ed intervals vvitli a series of circular clip-Shaped depiesios 15for Containing p -r e enculer eupisnapd dpressions in the operation ofthe Wax' have tendenoy to dravv togtliermthe fibres f the leather f the"shoe Solev or'fhel lift;` A sleeve 16l is thre'adedly mounted upon thesmaller shankpotiorf of the' head and is adjustable by rotationtnere'along'. The end of this sleeve "isp'roVidd with a'n `enlargedinside diameter' providing a recess 16o for enclosing the end of thetool iiead and constituting a gage 17 for the Waxer WQ In the normaloperation of the tool, the shoe being operated upon will be presentedfirst to the trimmerand then to the Waxer. In order that the adjustmentof the trimmer gage and vvaXer gage may be effected simultaneously andto the same extent, pins 19 are fastened into the end of the cylindricalring 13 located within the recess 12 and these pins extend throughopenings 20 and project into the recess 16d alcove the ledge 21 deningthe face connecting the reduced and the enlarged sections of the head.The pins 19 extend through openings in a ring 23 surrounding the smallercircumference of the tool head. The pins are provided with heads 19a,and coil springs 25 bear at one end against the ledge 21 and at theother end against the ring 23 so as to hold the pin heads in engagementwith the bottom ofthe recess 16a dened by the sleeve 16. By thisarrangement when the sleeve 16a is rotated along the threads upon thetool head to adjust the position of the WaXer gage 17, the trimmer gage,13 is simultaneously adjusted. In the left hand travelof the sleeve 16the trimmer gage 13 is positively moved forward by reason of theengagement of the bottom of the recess 16a of the sleeve 16 with the pinheads 19a; while in the right hand, or retractive, movement of thesleeve the gage 13 is restored by the springs to a position limited bycontact of the pin heads 19a With the bottom of the recess.

I claim:

1. A combined trimmer and Waxer comprising a head mounted upon arotatable drive shaft, a series of cutting blades circumferentiallyspaced about the head, a cylindrical work-engaging surface provided witha plurality of depressions adapted to contain Wax, a gage adjacent saidcutting blades and a gage adjacent said cylindrical Work-engagingsurface, and means operable for simultaneously adjusting both of saidgages to vary the extent of the Work presentable to the cutting bladesand to the Work-engaging surface.

2. A combination tool comprising a head adapted to be mounted upon arotatable drive shaft, a trimmer and Waxer located at spaced intervalsalong said head, said trimmer comprising a series of cutting bladescircumferentially spaced about the head and said Waxer comprising afriction cylinder located adjacent said trimmer, an adjustable gage forsaid trimmer and an adjustable gage for said Waxer adapted to limit theapproach of the work to said trimmer and Waxer respectively, and meansfor simultaneously adjusting these two gages.

3, A combination tool comprising a head adapted to be mounted upon arotatable drive shaft, a trimmerand a Waxer located at spaced intervalsalong said head, said trimmer comprising a series of cutting bladescircumferentially spaced about the head and said Waxer comprising afriction cylinder located adjacent said trimmer, an adjustable gage forsaid trimmer and an adjustable gage for said waxer adapted to limit theapproach of the Work to said trimmer and waxer respectively, said gagesbeing displacable longitudinally of the head, the arrangement being suchthat movement of one of the gages imparts movement to the other gage,and means for adjusting one of said gages.
